Achieving the Perfect Refrigerator Temperature

Temperature is the degree of heat present in a substance or object. Refrigerator temperature is the degree of heat present inside a refrigerator cabinet. Refrigerator temperature is measured in Fahrenheit and Celsius. 

Whether using a refrigerator at home for storing food and drink, a medical refrigerator in a lab or hospital for storing medication, or a commercial refrigerator in a store or restaurant, it's important that the fridge is set to the right temperature. If the refrigerator temperature is too warm or too cold, it could spoil food or destroy sensitive drugs and vaccines.

Here are some common refrigerator temperature ranges for different uses:

  • Medications: 45 to 59° F
  • Refrigerated Vaccines: 32 to 40° F
  • Frozen Vaccines: Below 32° F
  • Breast Milk: 77°F (countertop), 40° F (Refrigerator), and 0° F (Freezer)
  • Food Refrigerator: 32 to 40° F (Refrigerator)
  • Food Freezer: Below 32° F (Freezer)

By keeping your refrigerator temperature within these recommended ranges, you will be able to safely store food, beverages, breast milk, vaccines, and drugs. 

It's not just the refrigerator temperature that's important. Refrigerators also need temperature stability so that items are kept at the right temperature the entire time they're stored, without sharp spikes or drops. For instance, when a fridge or freezer door is opened multiple times, it can cause a change in temperature, impacting temperature stability. 

The temperature also needs to be uniform throughout the entire refrigerator cabinet. In some fridges, the temperature could be a little too high or too low on the top or bottom shelves. It's unsafe to store food, beverages or drugs at these spots, since it puts customers and patients at risk and potentially wastes usable storage space.

Achieving the Perfect Refrigerator Temperature

Phononic is an innovative refrigeration company that uses semiconductors to provide solid-state cooling. Our refrigerators deliver greater efficiency, capacity, temperature uniformity, and overall quality than compressor-based fridges. With a Phononic refrigerator or freezer, you can be sure that temperatures stay in range. Phononic provides exceptional temperature monitoring through remote and local data logging (that meets CDC guidelines) to ensure consistent temperatures even with frequent door openings. Temperatures are uniform throughout the entire fridge, so you can take advantage of all storage space without worrying about hot spots or freeze zones.
